基础题：复选框多列的形式怎么做？

Question

while($row = mssql_fetch_array($rs)){
echo "<tr>";
//for($n=1;$n<3;$n++){
echo "<td><input id=\"D[]\" name=\"A[]\" type=\"checkbox\" value=\"$row[ID]\" />$row[Name]</td>";
}
echo "</tr>";
// }
这样的话就是每行重复两个 呵呵 不可以

Answer 1

   echo "<tr>";
while($row = mssql_fetch_array($rs)){
                             
                                //for($n=1;$n<3;$n++){
                                    echo "<td><input id=\"D[]\" name=\"A[]\" type=\"checkbox\" value=\"$row[ID]\" />$row[Name]</td>";
                                    }
                                    echo "</tr>";
                                //    }
你现在不就是多列吗？

Answer 2

$i=0;
while($row = mssql_fetch_array($rs)){ 
                             echo "<tr>";                             
                                //for($n=1;$n<3;$n++){
                                    echo "<td><input id=\"D[$i]\" name=\"A[$i]\" type=\"checkbox\" value=\"$row['ID']\" />$row['Name']</td>";
                                    }
                                    echo "</tr>";
  $i++;
                                //    }

Answer 3

$i=0;
while($row = mssql_fetch_array($rs)){ 
                             echo "<tr>";                             
                                //for($n=1;$n<3;$n++){
                                    echo "<td><input id=\"D[".$i."] name=\"A[".$i.]" type=\"checkbox\" value=\".$row['ID'].\" />".$row['Name']."</td>";
                                    }
                                    echo "</tr>";
  $i++;
                                //    }要注意单双引号!

Answer 4

$列数 = 3;
$col = 0;
while($row = mssql_fetch_array($rs)) {
  if($col == 0) echo '<tr>';
  echo "<td><input name='A[]' type='checkbox' value='$row[ID]'>$row[Name]</td>";
  $col = ($col + 1) % $列数;
  if($col == 0) echo '</tr>';
}
